Description

Spring clip

Technical field

The utility model is related to a kind of fixture, especially a kind of spring clip.

Background technology

Spring clip be the restoring force by the use of spring as the power closed up, two clamps being hinged be typically all by metal system Into metal is easily conductive, while the finish of metal package is higher, directly using easy skating.

Therefore, present spring clip can be equipped with sleeve in the handle position of clamp, and one is pinched or holding side for hand Just, another is also for safety, it is to avoid the shank of metal scratches hand.Current sleeve is typically all to be made of plastics, handle Set is with shank mainly by the way of interference is shunk and held tightly, and after the sleeve of stretching expansion for a long time, sleeve can loosen, easily from handle Portion is come off, and influence is used.

In order to solve this problem, people coat glue inside sleeve or outside shank, sleeve postpones increase with shank set Glue bonding, but easily hardened after glue bonding, it is easily deformed by shock, sleeve departs from shank, connection is reliable Property is not still high.

The content of the invention

The utility model solves existing spring clip shank and is nested with the connected mode that sleeve shrinks holding using interference, long After time use, sleeve easily comes off the defect for influenceing to use there is provided a kind of spring clip from shank, and shank afterbody sets protrusion Portion, sleeve tail end sets recess, protuberance and recesses fit formation backing stop structure, improves sleeve and shank connection reliability.

The utility model is also solved between existing spring clip sleeve and shank by glue bonding, sleeve or easily from Shank comes off the relatively low defect of reliability there is provided a kind of spring clip, and shank afterbody sets protuberance, and sleeve tail end sets recess, Protuberance and recesses fit formation backing stop structure, improve sleeve and shank connection reliability.

The utility model solves the technical scheme that its technical problem used：A kind of spring clip, including two folders being hinged Body, the shank of clamp is equipped with sleeve, and clamp shank tail end is provided with kink, and in the end edge formation protuberance of kink, Sleeve is provided with the recess as shank retaining close to bottom position, is formed and protuberance between recess and sleeve bottom interior surface The stop portion of cooperation.Stop portion is between recess and sleeve bottom interior surface, therefore recess turns into the side rib of stop portion, After protuberance coordinates with stop portion, recess stops protuberance, it is to avoid sleeve is come off from shank, and sleeve is connected reliably, no with shank It is easy to fall off.

Preferably, recess is to sleeve inner recess, concave side wall where the outer surface opposed recesses of recess.

Preferably, the bottom of sleeve is closed, the position between sleeve recess and sleeve bottom interior wall is provided with out Groove, slots as described stop portion.Neck is easy to connect as stop portion and protuberance socket connection.

Preferably, the equal length of the width of recess and fluting, the length of fluting is adapted with the length of protuberance.

Preferably, protuberance is plugged with fluting, protrusion end surface protrudes the outer surface 0-1mm of sleeve recess, sleeve The outer surface of side where recess is beyond protrusion end surface 1-1.5mm.It thus is avoided that protuberance stretches out from the surface of sleeve, not shadow Sound is used.

Preferably, shank cross section is in flute profile, two support body notches are relative to be hinged, kink closing flute profile tail end.

Preferably, kink sets pelmatozoa to be recessed in the both sides of protuberance, shank is recessed from the lateral handle of protuberance two The inner surface extension of portion two side.

Preferably, the position of sleeve correspondence shank depression is provided with fin, between fin and sleeve two side inner surface Sleeve depression is formed, sleeve depression is adapted with the two side of shank.

Preferably, the edge of shank two side is provided with tooth form mouthful, tooth form mouthful is triangular in shape, tooth form mouthful triangle Drift angle is towards the front end of clamp.Tooth form mouthful is in contact with sleeve inner wall surface, prevents sleeve from sliding.

Preferably, the width at sleeve opening is big, and it is gradually reduced towards sleeve bottom, the change in size and handle of shank The change in size of set is identical；There is chuck portion the end of clamp by hinge, and chuck portion has a clamping plane, two clamps The clamping plane in two chuck portions of end is relative.

The beneficial effects of the utility model are：Stop portion be between recess and sleeve bottom interior surface, therefore recess into For the side rib of stop portion, after protuberance coordinates with stop portion, recess stops protuberance, it is to avoid sleeve comes off from shank, handle Set is connected reliably with shank, difficult for drop-off.

Embodiment

Below by specific embodiment, and with reference to accompanying drawing, the technical solution of the utility model is made more specifically It is bright.

Embodiment：A kind of spring clip（Referring to Fig. 1 Fig. 2）, including two clamps 2 being hinged, hinge point is provided with torsion spring 5, There is chuck portion 4 end of clamp by hinge, and chuck portion can be rotated around bearing pin, and chuck portion has a clamping plane, two The clamping plane in two chuck portions of clamp end is relative.The shank of clamp is equipped with sleeve 1, and shank is that anticreep is connected with sleeve.

Shank cross section is in flute profile, and two support body notches are relative to be hinged, and clamp shank tail end is provided with kink 7, kink Close flute profile tail end.The end edge formation protuberance 10 of kink, the both sides of protuberance set pelmatozoa to be recessed 11, shank depression from The lateral shank two side inner surface extension of protuberance two.The end of protuberance is stretched out outside the notch edges of shank, protuberance it is curved Knuckle degree be more than kink bending angle, i.e., protuberance from kink end edge towards shank flute profile in bend.Shank two side Edge be provided with tooth form mouthfuls 6, tooth form mouthful is triangular in shape, and the drift angle of tooth form mouthful triangle is towards the front end of clamp.

Sleeve is provided with the recess 9 as shank retaining, shape between recess and sleeve bottom interior surface close to bottom position Into the stop portion coordinated with protuberance.Recess is to sleeve inner recess, concave side wall where the outer surface opposed recesses of recess.Handle The bottom of set is closed, and the position between sleeve recess and sleeve bottom interior wall is provided with fluting 8, slotted as described retaining Portion.The equal length of the width of recess and fluting, the length of fluting is adapted with the length of protuberance.Protuberance is mutually inserted with fluting Connect, protrusion end surface protrudes the outer surface 0.8mm of sleeve recess, the outer surface of side where sleeve recess is beyond protrusion end surface 1.2mm.The position of sleeve correspondence shank depression is provided with fin 12, sleeve is formed between fin and sleeve two side inner surface recessed Fall into, sleeve depression is adapted with the two side of shank.

Width at sleeve opening is big, and is gradually reduced towards sleeve bottom, the change in size of shank and the size of sleeve Change is identical.

Shank is inserted into sleeve, and kink is abutted against with sleeve bottom interior wall, and protuberance is inserted into fluting and stretched out To outside recess outer surface, fin is recessed with shank to be coordinated.

Embodiment described above is a kind of preferred version of the present utility model, not makees any shape to the utility model Limitation in formula, also has other variants and remodeling on the premise of without departing from the technical scheme described in claim.
